GROUNDING INSTRUCTIONS
The following provides grounding instruction information from the Underwriters’ Laboratory UL60950
Standard for Safety of Information Technology Equipment Including Electrical Business Equipment, Third
Edition, of December 1, 2000.
An equipment grounding conductor that is not smaller in size than the ungrounded branch-circuit supply
conductors is to be installed as part of the circuit that supplies the product or system. Bare, covered, or
insulated grounding conductors are acceptable. Individually covered or insulated equipment grounding
conductors shall have a continuous outer finish that is either green, or green with one or more yellow
stripes. The equipment grounding conductor is to be connected to ground at the service equipment.
The attachment-plug receptacles in the vicinity of the product or system are all to be of a grounding type,
and the equipment grounding conductors serving these receptacles are to be connected to earth ground at
the service equipment.
A supplementary equipment grounding conductor shall be installed between the product or system and
ground that is in addition to the equipment grounding conductor in the power supply cord.
The supplementary equipment grounding conductor shall not be smaller in size than the ungrounded
branch-circuit supply conductors. The supplementary equipment grounding conductor shall be connected
to the product at the terminal provided, and shall be connected to ground in a manner that will retain the
ground connection when the product is unplugged from the receptacle. The connection to ground of the
supplementary equipment grounding conductor shall be in compliance with the rules for terminating
bonding jumpers at Part K or Article 250 of the National Electrical Code, ANSI/NFPA 70. Termination of
the supplementary equipment grounding conductor is permitted to be made to building steel, to a metal
electrical raceway system, or to any grounded item that is permanently and reliably connected to the
electrical service equipment ground.
The supplemental grounding conductor shall be connected to the equipment using a number 8 ring terminal
and should be fastened to the grounding lug provided on the back panel of the equipment. The ring
terminal should be installed using the appropriate crimping tool (AMP P/N 59250 T-EAD Crimping Tool
or equivalent).

MOUNTING OPTIONS
The ATLAS 550 unit may be used on a tabletop or installed in a 19-inch or 23-inch rackmount or
wallmount configuration. ADTRAN includes 19-inch rackmount ears with the ATLAS 550 shipment
(23-inch rackmount ears are sold separately). For a rackmount installation, the ATLAS 550 allows
flush-face mount, face-forward mount, center mount, and rear mount. The rackmount ears may also be
turned face down for wall mounting. When wall-mounted, the ATLAS 550 unit may be installed with
either side up and the front and back panels facing sideways.
Rackmounting the ATLAS 550
The ATLAS 550 is a rackmountable unit which can be installed into 19- or 23-inch equipment racks. (The
ATLAS 550 ships with 19-inch rackmount ears installed; 23-inch rackmount ears can be ordered from
ADTRAN - P/N 3265379-2@C). Follow these steps to mount the ATLAS 550 into a rack:
